Magnetite can be produced as a byproduct of copper operations, and as such is recovered from the concentrator floatation tails stream by magnetic separation. Typically 15% by weight of magnetite is removed through coal washing and recleaning the magnetic .

Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from runofmine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.

Statistical analysis showed that all the four variables, the wash water, the time of washing, the screening velocity, and the relative density of medium all had a significant effect on the % of magnetite lost. The interactions between wash water and screening velocity, wash water and the coal type, screening velocity and coal type, relative ...

For traditional plant we offer the STEINERT WDS wet drum magnetic separators, which are optimised for the recovery of magnetite and ferrosilicon from the heavy media of the sink/float separators. In this way, traditional coal washing can be performed economically, through the recovery of the heavy media.

Coal Washing. When it comes to coal washing, RPM Solutions has the ability to provide superior solutions through our vast knowledge of the coal industry. A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded size chunks and stockpiles grades, preparing it for transport to market.

Coal washing. Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned.

Coal mining industry. For the separation of coal from waste, dense medium baths were used. This technique employed the difference in densities between coal ( tonnes per m³) and shales ( tonnes per m³). In a medium with intermediate density (water with magnetite), stones sank and coal .

for magnetite is in the densemedium washing process used in most coal preparation plants (Doral Resources NL 1990). This requires a suspension of finely milled magnetite in water. Magnetite is particularly wellsuited to this application, because of its high density and recoverability by magnets for recycling (Evans 1993). Magnetite for coal ...
